yugu updated PARQUET-1014:
--------------------------
Priority: Major (was: Minor)
Description:
Been looking through the repo and cannot find an example for multiple row group
writer.
Probably missed that. Would be great if you guys can point it out ! : D
Thanks!
was:
Error when trying to write multiple row groups and declare column writer
(compile passes tho running into mem mapping issue)
I've been trying to do something like write several int/double columns, yet the
second declaration of writer of the same type using next column crashes.
eg. say I have [int64.int64.int64,...double,double]
for (int __c = 0; __c < #columns; __c++)
{
if (type == int64)
{
parquet::Int64Writer* int64_writer =
static_cast<parquet::Int64Writer*>(rg_writer->NextColumn());
}
else if (type == double)
{
parquet::DoubleWriter *double_writer =
static_cast<parquet::DoubleWriter *>(rg_writer->NextColumn());
}
}
I've been looking through the examples in parquet-cpp repo but could not find a
fix (or similar example).
Issue Type: Improvement (was: Bug)
Summary: Example for multiple row group writer (cpp) (was: Conflicts
in declaring Column Writer of same type)
